MARYLAND, ASSIGNORS TO GELANESE CORPORATION OF DELAWARE "AND HERBERT PLATT, OF CURB OEAMEBICA, A (XJRPORATION METHOD OF TREATING TEXTILE MATERIAL AND PRODUCT THEREOF Ho Drawing. Application filed July 80,

from the following detailed description.

In accordance with our invention we reduce the lustre of textile materials containing yarns of organic derivatives of cellulose by applying thereto a substance containing an ethanolamine, and then subjecting the same to the'action of a hot aqueous medium, such as steam under pressure ,or steam under atmospheric pressure superheated to 101 C. or more.

it) The textile material to be treated in accordance with our invention may be a woven or knitted fabric, or it may be in. the form of yarn. The textile material may contain filaments of organic derivatives of cellulose such as organic esters of cellulose and cellulose ethers. Examples of organic esters of cellulose are cellulose acetate, cellulose formate, cellulose propionate and cellulose butyrate, while examples of cellulose ,ethers are ethyl cellulose, methyl cellulose and ben; zyl cellulose.

g If desired, the textile material may be a mixed material containing arns of organic derivatives of cellulose anci 'yarns of other fibres such as cotton, natural silk, reconstituted cellulose, wool, etc. i

In order, to reducethe lustre, a substance containing an ethanolamine is applied to a the organic derivative of cellulose material? While we have found that the best resultsare. attained by employing triethanolamine,

yet diethanolamine or monoethanolamine.

may be employed with advantage, particularly in admixture with the triethanolamine.

Preferably these materialsv are applied in the presence of some waters A If desired,ithe fabric or yarn' of organic derivative of cellulose may have its lustre" reduced over the whole surface thereof by the 1929. Serial m5. seam.

immersion of the same in an aqueous solution containing triethanolamine. For differential lustre efi'ects,the substance containing the triethanolamine may beappliedlocally, either by brushing or spraying through stencils, or by printin in the form of a paste containing a suitab e thickener such as starch, British gum, etc.

Yarn may be delustered by our process and the delustered yarn may be associated by Weaving with yarns of normal lustre, whereby fabrics havin difi'erential lustre efl'ects ma be produce Thus if such yarns of di erent lustres are woven in a jacquard loom, a fabric having lustrous patterns against delustered back ound or vice versa may be produced. By ocally applying the substance containing triethanolamine to yarn, yarnof differential lustre may be produced, which may be woven into fabric having beautiful efi'ects.

If a suitable dyestufi is added to the substance'containin the triethanolamine, further enhanced e ects may be obtained. For instance, if a paste containing the triethanolamine and the dyestuif is locally applied to the fabric, colored delustered patterns against a lustrous uncolored background are produced.

In the execution of our invention, we have found that after the application of the substance containing the triethanolamine, the

same should preferably be subjected to the hot steam without intermediate drying, since if the textile material is dried after the application of the triethanolamine and then steamed, theamount of delustering produced is considerably diminished.

In order further to illustrate our invention but without being limited thereto, the following specific-examples are given.

I Example K I A .A fabric consisting wholly of yarns of cellulose acetate is padded wih an aqueous solution containing 10% of triethanolamine. The fabric is then' immediately subjected to the action of steam at 5 lbs. pressure for 15 mindelustered.

Corn starch thickener (1:15)

utes in a cottage steamer. The fabric is well Example [I I A fabric consisting wholly of cellulose acetate yarn is printed by means of engraved rollers havin suitable designs with a paste made up as ollows:

35 parts by weight British gum thickener (1:1)

parts by weight Tricthanolamine 10 parts by weight The fabric is immediately without drying, subjected to the action of steam at 10 lbs. pressure for 15 minutes in a cottage steamer. That part of the fabric to which the paste has been applied has its lustre very much reduced, thus producing delustered patterns against lustrous background.

' Ewample'lll A fabric consisting wholly of cellulose ace tate yarn has locally applied thereto the following paste:

' British gum thickener (1:1)

- I 15 parts by weight Glycerine.

- 5 parts by weight Triethanolamine N 5 parts by weight As an Example II, the fabric is immediately subjected to the action of steam at 10 lbs. pressure for 15 minutes, and delustered' patterns against lustrous background are produced.

, It is tobe understopd that the foregoing detailed description is given merely by way of illustration, and that many variations may l be made therein, without departing from the spirit of our invention. p Having described our invention, what, we claim and desire to secure by Letters Patent 1.
